which is the improvement to add a `styleClass` property to nodes so that you
would be able to use normal CSS class syntax to apply these, e.g.:
<stylesheet>
text.gray {
color: #666666;
}
text.red {
color: #ff0000;
}
</stylesheet>
Since you seem to have separately invented the name `styleClass`, that seems
like a logical choice!
And, if you plan to use this feature pervasively in webtop, I'd make this a
hi-prio improvement to do, so we can have the 'real' syntax we want right away.
